Simple and versatile. Since it is new "technology" for me, I must use it with some guidance to understand all its utility, so the tutorials that are included will be handy without having to go to school to learn it.

What you pay for is what you get but it is worth it and for you to operate this software to the full capacity you have to learn about it, in the long run, knowledge is power.

I really appreciate how streamlined and… I really appreciate how streamlined and easy it is to fill out tax docs! Makes it so much more hassle free. My only issue is that it's a 100% free service, as I wish this was something the IRS did a long time ago.

By my own ineptitude I was having trouble printing a document. I thought I had to upgrade and then found out I didn't have to. So I reached out to get a refund and keep my original subscription and got that refund in MINUTES! I am a VERY happy, satisfied subscriber! And, I'm getting better at it :)

Pdffiller has by far the best support… Pdffiller has by far the best support team that I have ever experienced. They can be contacted day or night to help resolve any problem or question I have had. They are fast and provide answers promptly. They even send links or videos to show you how to solve the problem. Pdffiller is great for sending fillable and signable documents used in the medical field because they offer hippa compliance, encryption and secure cloud storage. I highly recommend pdffiller.

What do you like best? I like how easy it is to load my documents into pdfFiller & the multiple option for export when I'm finished. What do you dislike? Not a fan of the constant email verification especially since I've been using it for 3 years now & this is something just started in 2020 (it seems) What problems are you solving with the product? What benefits have you realized? I don't have a fax so its much easier for me to receive email documents, sign them with the signature feature in pdfFiller, and send directly to the recipient from the program. I get a notification, too, telling me my document has been downloaded. This has helped me a lot lately.
